En prenant l'article "Certitude" pour point focal, on veut donner à voir comment Diderot a su rassembler toute la puissance critique de l’Encyclopédie pour bousculer les certitudes de ses contemporains. Une lecture attentive de l’article permettra de voir comment Diderot se livre une composition singulière faite de pièces empruntées à des autorités. On verra ensuite que Diderot fissure lui-même ce collage en le mettant en dialogue avec des éléments externes selon une méthode sophistiquée de renvois à d’autres articles de (...) l’Encyclopédie ou à d’autres textes de collaborateurs du dictionnaire.

Quasi-realists aspire to accommodate core features of ordinary normative thought and discourse in an expressivist framework. One apparent such feature is that we can be more or less confident in our normative judgments—they vary in credence. Michael Smith has argued that quasi-realists cannot plausibly accommodate these distinctions simply because they understand normative judgments as desires, but desires lack the structure needed to distinguish these three features. Existing attempts to meet Smith’s challenge have accepted Smith’s presupposition that the way to meet (...) the challenge is to show that normative judgments have more structure than they initially seem to have. I argue that accepting this presupposition is accepting too much. The orthodox view of certitude, insofar as there is one, understands certitude very roughly in terms of counterfactual betting behaviour. Counterfactual betting behaviour, though, is not in any useful sense a structural feature of a given judgment. It is rather a more holistic feature of a given agent’s cognitive system. Insofar as it can meet the other challenges it faces, quasi-realism can characterize credences in terms of counterfactual betting behaviour and effectively say exactly what many realists will want to say about credences, thus meeting Smith’s challenge much more directly.

De l'antiquité à la Renaissance, la notion de certitude est au coeur de la structuration de la pensée. Cet ouvrage réunit les contributions de spécialistes, qui explorent tous la littérature latine en mettant cette notion à l'épreuve de différentes disciplines et époques.

I’ve been both fascinated and distressed by the arguments raging over how best to respond to the covid-19 pandemic. In particular, I’ve been struck by the way people claim scientific authority for their confident assurances of what needs to be done. And I’m especially intrigued by the scorn they often lavish on those who hold differing views on what science is telling us. The heat generated by the resulting debates is strikingly similar to the heat generated by debates over the (...) science connected with human-caused climate change. And in both cases, the disputants too often presuppose indefensibly naïve views about scientific authority and certitude, apparently unaware that even the allegedly most obvious logical truths lack the certainty attributed to scientific authority in these debates. As a rule, I dislike re-circulating my Editorials, but I think it’s time to resurrect one (modestly tweaked) from a few years ago, addressing precisely this issue (Vol. 31, No. 3, pp. 379–386, 2017). …………………………………… “Man is a rational animal who always loses his temper when he is called upon to act in accordance with the dictates of reason.” --Oscar Wilde I’ve often noticed how debates within the SSE community sometimes parallel debates in the political arena, perhaps especially with respect to the passion they elicit and the intolerance and condescension sometimes lavished on members of the “opposition.” Occasionally, of course, the debates in the SSE are nearly indistinguishable from those in the political arena—say, over the evidence for human-caused climate change. But what I find most striking is how the passion, intolerance, etc.—perhaps most often displayed by those defending whatever the “received” view happens to be—betrays either a surprising ignorance or else a seemingly convenient lapse of memory, one that probably wouldn’t appear in less emotionally-charged contexts. What impassioned partisans tend to ignore or forget concerns (a) the tentative nature of both scientific pronouncements and knowledge claims generally (including matters ostensibly much more secure than those under debate), as well as (b) the extensive network of assumptions on which every knowledge claim rests. So I’d like to offer what I hope will be a perspective-enhancer, concerning how even our allegedly most secure and fundamental pieces of a priori knowledge are themselves open to reasonable debate. A widespread, but naïve, view of logic is that no rational person could doubt its elementary laws. But that bit of popular “wisdom” is demonstrably false. And if that’s the case, then so much the worse for the degree of certitude we can expect in more controversial arenas. Let me illustrate with a few examples.[1] [1] I’m indebted to Aune, 1970 for much of what follows. (shrink)

When William of Ockham lectured on Lombard's Sentences in 1317-1319, he articulated a new theory of knowledge. Its reception by fourteenth-century scholars was, however, largely negative, for it conflicted with technical accounts of vision and with their interprations of Duns Scotus. This study begins with Roger Bacon, a major source for later scholastics' efforts to tie a complex of semantic and optical explanations together into an account of concept formation, truth and the acquisition of certitude. After considering the challenges (...) of Peter Olivi and Henry of Ghent, Part I concludes with a discussion of Scotus's epistemology. Part II explores the alternative theories of Peter Aureol and William of Ockham. Part III traces the impact of Scotus, and then of Aureol, on Oxford thought in the years of Ockham's early audience, culminating with the views of Adam Wodeham. Part IV concerns Aureol's intellectual legacy at Paris, the introduction of Wodeham's thought there, and Autrecourt's controversies. (shrink)

José Antonio Valdivia Fuenzalida | Résumé : Pendant le xiiie siècle, plusieurs auteurs scolastiques ont adopté des théories aristotéliciennes pour expliquer la connaissance humaine. Ces théories supposent que l’homme est capable d’acquérir la science en se servant de ses forces naturelles. Notre âme est capable de saisir l’essence des choses en obtenant une connaissance certaine à leur propos. Pourtant, un bon nombre de ces auteurs estimaient que, même en admettant les théories mentionnées, on ne saurait se passer de l’assistance de (...) Dieu afin d’expliquer l’acquisition des connaissances scientifiques. Cet article s’interroge sur les raisons qui ont conduit lesdits auteurs à adopter une telle position. L’analyse de certains textes de saint Bonaventure permet de comprendre ce que la doctrine de l’illumination divine veut expliquer, à savoir : que nous pouvons obtenir de la certitude malgré le fait que les choses créées ne possèdent qu’une « nécessité conditionnelle ». En effet, même l’essence des choses créées n’aurait pas le degré minimum de nécessité qui est requis pour fonder la certitude absolue présupposée dans le concept médiéval de scientia. |: During the 13th century, several scholastic authors adopted Aristotelian theories to explain human knowledge. These theories assume that man is capable of acquiring science by using his natural powers. Our soul is able to grasp the essence of things by obtaining a knowledge that is certain about them. Yet, many of these authors believed that even admitting those theories, God’s assistance could not be dispensed with in order to explain the acquisition of scientific knowledge. This paper examines the reasons that led these authors to such a position. The analysis of several texts by St. Bonaventure allows one to understand what the doctrine of divine illumination aims to explain : namely that we can obtain certainty in spite of the fact that created things only possess a “conditional necessity”. Indeed, even the essence of created things would not have the minimum level of necessity that is required to be the foundation of the absolute certainty presupposed in the medieval concept of Scientia.

L’examen de certains manuscrits inédits du Fonds Foucault déposé par Daniel Defert à la BnF, en 2013, montre que le Descartes de Foucault est une variante simplifiée de celui de Heidegger. Foucault reprend en effet à la lecture heideggérienne de Descartes la liaison que le philosophe allemand met en place entre la mathesis universalis et le cogito, qui ne se trouve assurément pas chez Descartes. C’est de cette manière que ces deux auteurs critiquent ce qu’ils mettent eux-mêmes au jour chez (...) Descartes – le sujet de la certitude – et qu’ils font de l’inquiétude l’affect historique propre à la pensée. La présente étude reconstruit le lien entre la mathesis et le cogito et la critique de la vérité comme certitude, tel qu’il est élaboré dans les cours de Heidegger sur Descartes, Augustin et Aristote, au début des années 20. La manière dont Heidegger établit ce lien suit l’évolution de la pensée de Heidegger, mais nous prenons le parti de mettre l’accent sur le cours sur Descartes de 1922-1923 (Introduction à la recherche phénoménologique), car dans les années 20, Heidegger fait de l’inquiétude la figure de l’ipséité. Nous reconstruisons en parallèle la manière dont Foucault intègre la lecture heideggérienne de Descartes à la sienne et comment il en déplace la signification, en évoquant certains textes connus de l’Histoire de la folie, mais aussi en analysant des manuscrits inédits de Foucault. Car le rapprochement que nous proposons entre les deux auteurs, tout comme la mise en relief de ce qui les distingue, se fait à la faveur de l’occasion historique que constitue la mise à disposition de textes qui étaient auparavant inédits. Et, en effet, les cours de Heidegger que nous analysons ont été publiés dans la Gesamtausgabe après la mort de Foucault, et leur traduction en français est toute récente. En procédant ainsi, nous voulons montrer comment la redéfinition contemporaine de la subjectivité s’est élaborée, au XXe siècle, à partir de la notion d’inquiétude, et plus spécifiquement de l’inquiétude historique.

The presence of Neoplatonism in contemporary french phenomenology has a pregnance that crosses its most relevant points. Jean-Luc Marion's work does not escape this. In this work we approach the marionian appropriation of Nicholas of Cusa's thought, in the light of his writing Certitudes négatives, with the intention of understanding the cusanu´s ignorant doctrine as a way of negative certainty.

In the late 19th century great changes in theories of light and electricity were in direct conflict with certitude, the view that scientific knowledge is infallible. What is, then, the epistemic status of scientific theory? To resolve this issue Duhem and Poincaré proposed images of fallible knowledge, Instrumentalism and Conventionalism, respectively. Only in 1919–1922, after Einstein's relativity was published, he offered arguments to support Fallibilism, the view that certainty cannot be achieved in science. Though Einstein did not consider Duhem's (...) Instrumentalism, he argued against Poincaré's Conventionalism. Hitherto, Einstein's Fallibilism, as presented at first in a rarely known essay of 1919, was left in the dark. Recently, Howard obscured its meaning. Einstein's essay was never translated into English. In my paper I provide its translation and attempt to shed light on Einstein's view and its context; I also direct attention to Einstein's images of philosophical opportunism in scientific practice.

Abū Ma'shar and al-Qābīsī were active astrologers and defenders of the scientific character of their discipline. They wrote works on criticisms brought forward against the discipline and challenged practitioners whom they considered as detrimental for the esteem and future fate of their science. Nevertheless, both writers can be seen as heirs to a single tradition of thought, which took its origins in Ptolemy's Tetrabiblios and developed largely independently of the religious or philosophical beliefs of a specific community. The arguments developed (...) for proving the scientific value of astrology are interesting in their own right, and merit further study not only by historians of science but also by historians of philosophy.

Just as we can be more or less certain that there is extraterrestrial life or that Goldbach’s conjecture is correct, we can be more or less certain about normative matters, such as whether euthanasia is permissible or whether utilitarianism is true. However, accommodating the phenomenon of degrees of normative certitude is a difficult challenge for non-cognitivist and expressivist views, according to which normative judgements are desire-like attitudes rather than beliefs. Several attempts have been made on behalf of non-cognitivism and (...) expressivism to meet the challenge Studies in metaethics, Oxford University Press, Oxford, 2007; Sepielli in Philos Stud 160: 191–207, 2012; Eriksson and Francén Olinder in Aust J Philos 94: 719–735, 2016). These attempts have all been found wanting. Michael Ridge has recently offered a quasi-realist solution, according to which expressivists can say exactly what cognitivists say about certitude, including normative certitude. In this paper, we explain the basic problem and Ridge’s quasi-realist solution. We then argue that the quasi-realist account of normative certitude faces severe difficulties that do not arise for cognitivist accounts, according to which normative judgements are beliefs.

In lieu of an abstract, here is a brief excerpt of the content:Scientism, Certitude, and the Recovery of PoliticsChristopher Justin Brophy O.P.In Natural Law and Human Rights, Pierre Manent begins his analysis of the contemporary political situation by discussing the intractable tension between the relativism surrounding moral action and the absolutism surrounding "human rights." Later, drawing heavily from Aristotle's Politics, Manent discusses the necessity of a command-obey structure to resolve the tension such that human beings can fruitfully engage in (...) political life. These two claims, one about the tension between relativism and absolutism and the other about the command-obey structure, are closely linked. If it is true that human beings have an innate need for authority, then it is also the case that the extreme abuses of that need, as they manifest themselves in the political realm, will be either wholesale embrace of such authority (absolutism) or wholesale rejection (relativism). We should be clear that the authority Manent discusses is not arbitrary or autocratic exercise of power, but a legitimate authority towards which citizens can offer rational assent. But any human need or desire can be abused and knowledge of the abuses is necessary to understand the proper object.It is the contention of this piece that Manent, in his explication of command-obey, wrote better than he knew. Manent authored his text before the COVID-19 pandemic. Yet, his analysis provides some of the best explanatory power for understanding the politics surrounding COVID. This politics has significance that transcends the particular crisis of the pandemic and merits serious attention. Specifically, Manent's analysis of the human need for a command-obey structure both offers an explanation for the concurrent tension between relativism and absolutism, at least as it pertains to the relationship between science and politics, and gives explanatory [End Page 239] power for the rise of scientism in contemporary society. The widespread conception that the natural sciences have the potential to answer questions that reside out of their proper purviews leads to abuses of authority in both directions, by both sides—the political left and political right. I will flesh out my argument first by showing the usefulness of Manent's analysis for explaining how easily so many in the United States fall prey to a false conception of "science" that undermines a healthy politics and reveals, at root, a dangerous aversion to ambiguity. I will then explain the implications of the elevation of scientism for the relationship between politics and Christianity. I will conclude with some reflections on the common good and the future of politics in the United States given Manent's important observations. I anticipate that a common criticism of Manent's book will be that it lacks clear prescriptions for the political problems that ail us. I will argue that clear prescriptions cannot follow from the logic of Manent's argument, and ultimately that the lack of prescription is one of the strengths of the book.Before I begin, I wish to make two qualifications. First, Manent's argument ultimately is about the (un)tenability of liberalism without some common conception of the good. He treats several moral and political problems in his book that fall outside of the scope of this short paper. I am not attempting in the analysis that follows to reduce the moral scope of Manent's claims or even to take up the mantle of his argument. I simply wish to show how his analysis is helpful in explaining a contemporary political problem and how the implications of this analysis should affect the way Christians think about political practice in the United States. Second, I want to make clear at the outset that I positively wish to avoid a discussion about the various policies enacted as responses to COVID-19. I also want to avoid any cavalier political discussion of COVID that does not sufficiently respect the over one million persons (given the latest CDC tally) who have lost their lives in this country and the hardships that many more have endured due to the pandemic. It is essential for our purposes here though to treat the political significance of the pandemic. I will attempt to do that now.The Appeal of ScientismNumerous thinkers... (shrink)

When paternalism is deemed morally justified, weak paternalism—which restricts itself to assisting the target of paternalism realize his own preferences—is the preferred (less problematic) alternative. In determining the appropriateness of weak paternalism, the level of certitude of the paternalist regarding the correctness of her assessment of the true preferences of the one‐paternalized is obviously a crucial factor. Yet in the ethics of paternalism this parameter has escaped systematic treatment. This paper aims to initiate discussion on this indispensable consideration for (...) weak paternalism. Analysing a real‐life dilemma of paternalism in healthcare, the paper focuses on the theoretical question of how the paternalist can optimize her certitude by combining personal knowledge of the individual patient with population data on treatment refusal/consent of patients facing similar decisions. The paper presents an outline of a decision‐making scheme that can be valuable in medical ethics and beyond. (shrink)

This Is A New Release Of The Original 1883 Edition.

The concept of ‘‘certitude” is central in Arabic discussions of the theory of demonstration advanced by Aristotle in the Posterior Analytics. In the Arabic tradition it is ‘‘certitude,” rather than ‘‘knowledge”, that is usually identified as the end sought by demonstrations. Al-Fārābī himself devotes a short treatise, known as the Conditions of Certitude, to determining the criteria according to which a subject can claim to have absolute certitude of any proposition. In this article the author traces (...) the roots of the concept of certitude to the Arabic translation of the Posterior Analytics. She then offers a close reading of the text of al-Fārābī's Conditions and its parallels in his Epitome of the Posterior Analytics. She argues that the identification of certitude as a cognitive state distinct from knowledge enabled al-Fārābī to introduce a number of interesting and sometimes problematic innovations into Arabic epistemology. Foremost amongst his positive innovations is the recognition that contingent as well as necessary propositions allow for an attenuated form of certitude, and the introduction of reliabilism into the justification of claims to certitude. But al-Fārābī is also one of the first philosophers to articulate explicitly the idea that certitude must include an element of ‘‘knowing that one knows,” a controversial principle that tends to undermine both al-Fārābī’s reliabilism and his efforts to loosen some of the strictures in traditional Aristotelian epistemology.

This article is a reflection on chance as a scientific object, starting from a materialistic point of view.

Claiming the legacy of revolutionary of 1789, the Republicans organise at the end of nineteenth century the French school in its modern form and developpe a philosophy that is “fondationnaire” placing educational institution as foundation of the nation. The idea of the emancipation of the people by rational instruction without neglecting the moral and civic education is well located in the heart of the French school project and aims abstract rational subjects, despite their unique characteristics and affiliations. The phrase “the (...) Republic will be educator or she will not! “claim this fundamentally political intent stay up until the Second World War. After this period, the school system begin to be invested by the economy; during the period of the welfare state, an original synthesis seems to occur between “republican meritocracy, [...] social equality mass...

This delicate balance then seems to break during the Twenty pitiful’s years, then the school is characterized by a multiplicating of its missions, the lost of landmarks and the difficulty to make sense. The actual siginification of the scholar system will be questioned regarding to economic and anthropological influence of neo-liberalism, the requirement for long life education and its consequences, and also the education-socialization-qualification relations.

Existe-t-il une tension entre la Loi de continuité (LC) d’Émilie du Châtelet et sa conviction qu’il existe une différence de nature entre les propositions absolument certaines et les propositions moralement certaines? Dans cet article, je soutiens qu’il n’y a pas de tension, car les commentateurs peuvent faire au moins deux choix d’interprétation. Tout d’abord, ils pourraient affirmer que pour du Châtelet, la LC ne devrait s’appliquer qu’au domaine empirique : il existe un fossé épistémique entre le monde naturel et empirique (...) à partir duquel nous obtenons des vérités moralement certaines, et le monde abstrait et métaphysique à partir duquel nous obtenons des vérités absolument certaines. L’autre alternative, que je défends ici, est la suivante : interpréter du Châtelet comme croyant en une formulation épistémologique de la LC, auquel cas (i) il n’y a pas de différence de nature entre les propositions absolument certaines et moralement certaines, et (ii) le domaine de toutes les vérités est constitué de toutes les vérités, même les vérités absolument certaines (contrairement aux positions de Brading en 2019, Detlefsen en 2014, et de Wells à venir). Cette interprétation résout la tension car elle signifie que du Châtelet n’est pas engagée – à proprement parler – dans une différence de nature entre les vérités absolument et moralement certaines, ce qui est donc cohérent avec une formulation épistémologique de la LC (puisqu’il n’y aurait pas de sauts ou de lacunes entre l’une et l’autre). Selon cette interprétation, il est en principe possible que des vérités moralement certaines deviennent des vérités absolument certaines, une fois que le Principe de contradiction (PC) ou Dieu est la raison suffisante pour laquelle les premières sont en fait absolument certaines.
